Busbar welding die

The busbar welding die comprises a machining frame, a hydraulic oil cylinder is installed in the middle of the top of the machining frame, an output rod of the hydraulic oil cylinder is connected with a sliding plate, an upper welding die mechanism is installed at the bottom of the sliding plate, and a lower welding die mechanism is installed on a bottom plate of the machining frame and comprises a lower welding die body. A first mounting groove is formed in the middle of the top of the lower welding die body, a clamping assembly is movably mounted in the first mounting groove, fixing assemblies are symmetrically arranged on the two sides of the top of the lower welding die body, thickness limiting blocks are symmetrically arranged at the two ends of the top of the lower welding die body, and pressing assemblies are arranged on the thickness limiting blocks. By the adoption of the structure, the first connecting part and the second connecting part of the busbar can be welded at a time, and compared with an ex
